Tom C., sorry I misread that you intended not to look for the black matrix in the non-operating condition.
If a tube is black-matrix, it definitely will not have NTSC green. The chroma electrical matrix (or equivalently, the demodulator gains and angles) can provide some correction and can give very pleasing color, but cannot make the green phosphor less yellow or improve the cyan saturation to the same level as a 15GP22. Also, the corrections that fix the hue range between red and green always result in making the reds brighter and the cyans darker than a tube with NTSC phosphors, as a result of the tube gamma characteristic.
